open_folder_as_group

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full behavioral burden. It signals a side-effecting action (opening tabs and creating a group) but says nothing about window targeting, behavior when the folder is empty or a group with that name already exists, or failure handling.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence, front-loaded with the action, with zero filler. The whole contract of the tool is conveyed without waste.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The output schema is present, so return values need not be explained, and the tool is simple with one parameter. However, with no annotations and an undocumented parameter, the description leaves failure modes and tab-placement behavior unspecified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 0% description coverage for the single 'folder' parameter. The description partially compensates by clarifying that the value is a bookmark folder and that its name is reused for the group, but it omits format, lookup rules, or whether a path/ID is accepted.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Specific verb (open) plus resource (every link in a bookmark folder) and the resulting state (tabs in a group named after the folder). It is clear what the tool produces, but it does not distinguish itself from close siblings like group_tabs, save_group, or organize_tabs.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The scenario is implied by the description (you have a folder of links and want them open as a group), but there is no explicit when-to-use, when-not-to-use, or named alternative among the many tab/group siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
